That function forwards the caller's argument via axios to an API_BASE_URL assembled at runtime from ~13 fragments produced by an obfuscator.io RC4 string-array decoder. The entire ~30 KB index.js is wrapped in the standard obfuscator.io scheme (RC4+base64 string array, hex-escaped literals, wrapped index accessors, array-rotation IIFE, and a self-defending RegExp function-body anti-tamper check) whose only purpose here is to hide the destination URL. The caller does not configure this destination and is not informed of it; normal use of the advertised API silently leaks the caller's cryptographic inputs to an author-controlled host.\n","affected":[{"package":{"ecosystem":"npm","name":"node_cryptography"},"versions":["1.0.0"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"index.js","sha256":"36818f21afa90fc408d190517e8aea61f86bd13f1b5b6523b1300879695ee689","tlsh":"76d2abd077d0e803568f4b63bf16b9e8e42a98ba34d8994bd150b98cb4bd507c5b4ef0"}],"package_integrity":[{"filename":"node_cryptography-1.0.0.tgz","hashes":{"sha1":"7fea3288b57dcbb6c6fe48e5268001fbcfc716a2","sha512_sri":"sha512-pRjmUqCzqJlKesFI0rZ3a0+O49w0Z3FVlC00owFtwcinCeSI54yh2Q3XVwwfbQgASigc50cA2uRHM4X8HsxDqA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/node_cryptography/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-018392","import_time":"2026-08-19T07:48:47.167746333Z","modified_time":"2026-08-19T07:43:47Z","sha256":"1e10a704c94a9f7a4f6344a67e3867cd87b21be574e81bbdccdc6b5ca48f65a2","source":"amazon-inspector","versions":["1.0.0"]}]}}
